downloading files from server to local folder in php

[increase]

I want to backup mp3 files from a server folder to a local folder can this be done in php which is server side.

I tried many scripts claiming to do this but all result in  'failed to open stream: No such file or directory' because the code is looking for the destination on the server, not the local directory.

Here is an example that says it can be done.

ini_set('display_errors',1);
error_reporting(E_ALL);

$source = "https://domain.com/2024-2021/path_to_file/test.mp3";
echo "src is ", $source;
$destination = "C:/backup/2024-2021/Cpath_to_file/";

file_put_contents($destination, file_get_contents($source));
echo "OK";

This one also claims to 'force' the download

$file = '/path/to/files/photo.jpg';
if (is_file($file))
{
    sendHeaders($file, 'image/jpeg', 'My picture.jpg');
    $chunkSize = 1024 * 1024;
    $handle = fopen($file, 'rb');
    while (!feof($handle))
    {
        $buffer = fread($handle, $chunkSize);
        echo $buffer;
        ob_flush();
        flush();
    }
    fclose($handle);
    exit;
}

But has the same problem, in that it fails when opening the local folder to write the file, is there a way to do this?

A remote server will not have access to your local file system, so no you cannot have your remote PHP script copy files to your local system.
